UAF student plunges into Iraq air quality PDF Print E-mail
Written by Brianna McNall   

Taurus & Zagros Mountain ranges bordering IraqAir quality is a hot topic in Fairbanks, where local residents contend with chimney smoke and car emissions in winter and wildfires in summer. But some of the biggest air pollution problems under scrutiny by Fairbabnks scientists are those threatening soldiers far from home.

Jennifer Bell, a Ph.D. student at the University of Alaska Fairbanks, studies air quality in Iraq with other graduate students in the Catherine Cahill lab group on campus.

Bell studies geogenic, or naturally occurring, sources of the particles that soldiers breathe.

“In Iraq you’re dealing with areas that have immense dust storms,” she said. “You’re looking at a large transport of soil across a major geological region.”

Heating the Ice PDF Print E-mail

Bernie Karl knew he wanted an ice museum. Karl felt an ice museum would be a great addition to Chena Hot Springs, the resort he owned 50 miles outside of Fairbanks. So in December of 2003, he contracted two experienced ice carvers, Steve and Heather Brice, a husband and wife ice-carving team to build his museum. Three months later, his idea was
completed, and he had his giant, cathedral-like ice museum.

But then summer came.Interior Gallery Photo by Denise Feree

With the nearly 90-degree Fairbanks summers, the Brices and Karl could do nothing but watch as the giant ice palace melted into a giant ice puddle. Karl was using a refrigeration system on the museum, 

but it was expensive, inefficient, and as the rubble and puddles suggested, not sufficient.

“It felt pretty disappointing,” Steve said, on the biggest project of his career at that point. “I had given up on it.”

But Karl hadn’t. In 2004, he came across an absorption chiller, a machine that uses hot water and ammonia to refrigerate. The Brices started to work again in September of 2004, and completed a second ice museum, but this time, with the absorption chiller. When the summer came, the museum stayed. Karl’s idea had worked. He used hot water from the springs to freeze water, and keep his museum on ice.

Last Saturday, UAF played host to a crowd that was smaller than usual - literally. School children from around Fairbanks flooded the halls of UAF Reichart Building for an afternoon of science fun.

First Person: Science is FUN at the UAF Science Potpourri PDF Print E-mail
Written by jane groseclose   

Imagine my surprise, (and joy) when I discovered the university still offered the “Science Potpourri,” an event open to the public, where children of all ages can experience science – in your face, hands-on, and most certainly fun. Kids move from station to station, set up with activities in practically all schools of sciensci-popori-2ce. All the stations are overseen by knowledgeable graduate students and professors of the CNSM department (College of Natural Science and Mathmatics) at the University of Alaska Fairbanks. Who seem to have as much fun as the kids.

Research funding deadlines are coming PDF Print E-mail
Written by Brianna McNall   

While February is the deadline for most academic scholarships, March and April are important months for science students at UAF. 

Many different private and public grants and scholarships are available for undergraduate and graduate researchers. Unfortunately, they can be a little hard to find. Here are just a few of them for science students.

March 25 is the deadline for nominations for the Brina Kessel Medal for Excellence in Science, and April 1 is the last chance for paleontology and archaeology students to apply for the UA Museum Geist Fund competition which awards up to $4000 in scholarships and fellowships. And April 18 is the last date to apply for the David and Rachel Hopkins Fellowship. Grants and scholarships can be a great plus for students with research project ideas.

Deadlines and links to these and other upcoming competitions can be found on the UAF Weekly Science Calendar.

Shock waves from earthquakes propagate in ways that most of us wouldn't expect. 

The Incorporated Research Institutions for Seismology posted an animation that might make things a bit clearer.
